Holiday fulfillment and returns collide as U.S. sales exceed $1 trillion
During the November‑December holiday period, operators confront overlapping outbound fulfillment and returns flows as U.S. holiday sales are projected to exceed $1 trillion and consumers return 14% of their purchases. Close to one in seven of those returns happen in the final six days of December, the same week outbound volume stays above typical levels.
Inbound docks become congested as returning goods arrive while outbound shipments still require receiving space, limiting the area available for put‑away. Warehouse flexibility shrinks because labor and square footage cannot be easily shifted between outbound and reverse processes when both peaks run concurrently. Transportation networks feel added pressure as carriers must move both outbound orders and return shipments through the same capacity, and seasonal labor pools are at their lowest level since 2009. Cross‑training becomes more valuable than deep specialization as workers need to switch between picking, packing, and inspecting returns throughout the shift.
In the past, fulfillment volumes built through November and December, with returns only rising after the outbound rush ended, letting operators handle shipping first and reverse logistics later. Earlier promotions, longer calendars, faster return initiation, and growth in omnichannel buying have merged the formerly separate peaks into a single, overlapping period. The traditional pattern of peak season no longer applies.
What we know

Consumers returned 14% of everything they bought between November 1 and December 31, and close to one in seven of those returns landed in the final six days of December, the same week outbound volume is still running at higher levels than typical.
In 2025, seasonal retail hiring was on pace for its lowest level since 2009, and warehousing and transportation added fewer seasonal positions than the year before, and
Earlier shopping windows, longer promotional calendars, faster return initiation and more omnichannel purchasing are compressing what used to be two separate peaks into one.
